CONVERTIBLE CHAIR Filed May 14, '1937 3 Sheets--Sheefl 3 vile( la?? (sz y 14% Patented Feb. 14, 1939 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to improvements in convertible chairs.

One of the objects of this invention is to provide a chair which normally has a back and side arms and is of the general proportions of an easy chair and which may be unfolded to present a strong and serviceable bed.

Another object of this invention is to provide a convertible chair which is strong, compact and of economical construction.

A further object of this invention is to provide a convertible chair which provides within itself a storage compartment for the usual articles of bedding, and especially a mattress which may be used in conjunction therewith.

A further object relates to the novel construction of the back of my chair which may be unfolded to comprise the completed bed and which is supported by the chair base and unfolded arm rest.

Other objects relate to details of structure and arrangement of parts which will be apparent from a consideration of the following specification and drawings, wherein:

Fig. 1 is a side elevation of my improved convertible chair in its normally closed position.

Fig. 2 is a side elevational View showing the seat and arm portion of the chair unfolded forwardly so that it is horizontally aligned with the base of the chair, the seat being supported by the arm rests.

Fig. 3 is a side elevation showing a further step in the conversion of the chair into the bed wherein the back of the chair has been swung forwardly and downwardly onto the base.

Fig. 4 is a further development of Fig. 3 showing a nested portion of the back unfolded therefrom and resting on the unfolded arms which form a support therefor.

Fig. 5 is a longitudinal sectional view of my convertible chair taken on line 5-5 of Fig. 6.

Fig. 6 is a sectional view taken on line 6 6 of Fig. 5.

Fig. '7 is a plan View of my device when completely opened up into a bed.

Fig. 8 is a side sectional elevation thereof.

Referring more in detail to the drawings, I0 indicates the base of the chair supported at its forward end by legs and at its backward end by legs l2. The forward legs Il extend directly underneath the forward corners of the base and the rearward legs I2 extend preferably from lateral extensions I3, at the rearward corners of the chair. A pair of side arm rests I4 are provided, whch may have a curvilinear contour tothe height of the base at said point towards the forward end, or of any desired decorative shape. The portions of the arm which extend backwardly towards the sides l5 of the back of the chair, may be formed horizontally v for a short distance, as at I6. the arm at the portion I6 from the upper edge of the arm to the bottom of the seat I'I is equal above the floor level.

The side arm supports |4 may be constructed 1 of solid side walls, or may comprise a horizontal rail carried by vertical supports at each end. The seat may be formed of a solid surface, or it may be formed in a rectangular outline and carry a seat cushion or upholstering. Likewise 1 a cushion or upholstering may be provided on the chair back, the arrangement of the cushion in this instance, however, being such that when the chair is converted, as will be later set forth, this cushion will nest into the base I. 2

The forward edge of the seat is provided with a hinge, as at I8, hinging it to the base ID so that the arms and seat may be turned outwardly on a vertical plane until the portion l5 rests on the oor and forms a support for the 2 seat. The back of the chair, generally indicated at I5, is also hinged to the base at I9 adjacent the seat level |'I, and after the arms have been completely unfolded the back may be turned in a vertical plane on its hinges until it rests on the 3 base portion l@ and partially on the unfolded seat as shown in Fig. 3. This back consists of two portions folded against each other as at 20 and 2|, the portion 2| nesting within the side walls I5 of the back which forms a concealment 3 therefor When the device is folded intoits chair position and gives the back a unitary appearance. A hinge 22 connects the back members 2|] and 2| at their upper ends so that the back member 2| may also be rotated in a vertical 4 plane to have one end abut against the adjacent end of section 20, and to extend horizontally therewith.

A head board 23 may be provided, which extends perpendicularly from the back section 2|. 4 When section 2l is closed against section 20 the head board extends slightly beyond the end of the side wall I5, and a mattress or the like which may be laid on the open back, may be retained thereby when the back is closed. stretched over 5 the inner faces of the portions 20 and 2| may be a covering of canvas or other like material, as at 24. Or, if desired, this may take the form of a suitable spring so that when the back portions 5 The height of :.5

are unfolded they will afford a firm yet yielding support as a bed.

It will thus be seen that with my improved construction a strong, rigid and compact bed may be combined with a convertible arm chair, each retaining its respective functions to the fullest extent. I preferably form my base IU of a box-like construction, that is, a considerable portion of its depth is enclosed on four sides so as to form a compartment therein which may be used for the storage of bedding, mattress, pillows, etc.

It will readily be seen that various changes may be made in the details of my construction and the arrangement of the parts thereof without departing from the spirit of my invention, and I therefore do not intend to be restricted thereto except as set forth in the following claim.

I claim as my invention:

In a convertible chair of the class described, an upwardly open hollow base portion, a seat hinged to said base at the forward edge thereof and being adapted to be turned on said hinge in a vertical plane and adapted to extend horizontally from said base portion, side arm rests extending from said seat and provided with a horizontally extending' portion at their rearward: ends and adapted to support said seat in its horizontally extended position, a back rest hinged adjacent its lower end to said base and normally abutting thereon and having a cushion extending forwardly from the plane thereof, the said back rest being adapted to be turned about its said hinge as a pivot in a vertical plane and to rest horizontally on the base portion with the said cushion nesting within the hollow thereof, side walls formed on said back rest and extending rearwardly therefrom and coextensive therewith, an extensible bed portion hinged to the top of said back rest and normally adapted to be carried thereby and to lie against it nested within said side walls, a iixed head board extending from the lower end of said bed portion adapted to extend over the lower end of said back rest to normally provide a retaining end closure, said extensible bed portion being adapted to pivot about its hinge and to lie extended in a horizontal position on said extended seat and to be supported thereby.
